Which also means "less chance of mistake". For example, if you decide
later to change "y" to "y1", you only have to change the code in one
place, not three. Functional "case" and "if" are not only from Ruby,
also from all functional languages (sml, ocaml), also Python and even C
have functional "if".

I'm not saying that this is some revolutional or essential feature.
But just because "we can work without it" doesn't mean it's totally
useless :)
